Incheon Pediatric Abdominal Pain

Our child keeps saying their stomach hurts, but the hospital says there's nothing wrong?

1. Why do they keep saying they're in pain?

Hello. This is Baekrokdam Korean Medicine Clinic.

Have you ever had these concerns?

My child keeps saying their stomach hurts.

It's not just once or twice; it happens several times a week, so we've been to the hospital multiple times.

Blood tests, X-rays, ultrasounds... the results are always "no abnormalities," but my child still says, "My tummy hurts."

Is this faking it? Or is there really something wrong?

2. Three Types Seen Through Cases

Child with Abdominal Pain Every Morning

This is a second-grader. Whenever they get ready for school, they complain of stomach pain, leading to frequent tardiness or absences. However, on weekends or during vacations, they are perfectly fine.

In such cases, it is highly likely to be functional abdominal pain, where stress or anxiety manifests as digestive symptoms.

Child Complaining of Abdominal Pain and Bloating After Meals

This is an older elementary school child who feels bloated whenever they eat. Even when they don't eat much, they always say, "My stomach feels uncomfortable." They are picky eaters and often seek water.

This could be related to 'functional dyspepsia'. It's a case where the stomach doesn't move well or stomach acid secretion is sensitive.

Child Waking Up Crying with Abdominal Pain at Night

They wake up in the middle of the night crying, saying their stomach hurts. We even went to the emergency room, but tests showed no major issues. By the next morning, they play as if nothing happened.

This can be seen as abdominal migraine or intermittent gastrointestinal spasms. This pattern is frequently observed in particularly sensitive children.

3. Functional Abdominal Pain is Not Faking It

'Functional abdominal pain' refers to a condition where there's no problem with the organs, but the pain is genuinely present. When a child's intestinal nervous system becomes sensitive, they experience significant pain even from minor stimuli and complain of recurrent discomfort. This is not simply a psychological issue, and it is certainly not faking it.

4. Six Things Parents Can Check

It's helpful to record the following six things:

  1. ① When does it hurt? Time of day such as morning / before meals / after meals / before bed
  2. ② Where does it hurt? Around the navel / epigastrium / flank / lower abdomen
  3. ③ What does the pain feel like? Squeezing / tightening / dull / burning
  4. ④ How often? Daily / 3 times a week / only in specific situations
  5. ⑤ Does it affect daily life? School absence / skipping meals / avoiding activities, etc.
  6. ⑥ Are there accompanying symptoms? Headache / constipation / vomiting / loss of appetite, etc.

Keeping a log of this will be a great help when visiting the hospital and effective in identifying your child's symptom patterns.

5. Types of Childhood Abdominal Pain from a Korean Medicine Perspective

In Korean medicine, we don't just look at symptoms; we also consider the child's constitution, personality, eating habits, and sleep rhythm.

Type Characteristics Key Points
Spleen-Stomach Weakness Type Poor appetite and low stamina Easily fatigued, cold hands and feet
Liver Qi Stagnation Type Sensitive and susceptible to stress Morning abdominal pain, stress-induced diarrhea
Food Stagnation Type Overeating or slow digestion Burping, constipation, bloating
Phlegm-Fluid Retention Type Pain on pressure, feeling of stomach blockage Thick white tongue coating, excessive sweating

Since children can express the same symptoms for different reasons, it's important to distinguish these patterns.

6. Before Treatment, Interpretation is Necessary

The first thing I tell parents in such situations is not to try to convince the child, but to record and observe.

What did they eat today, when did their stomach start hurting, were there any incidents at school, did they sleep well... when these small pieces of information are consistently recorded, your child's body rhythm begins to emerge.

Don't just listen to "the hospital said there's nothing wrong"; you need to try to interpret your child's expressions. This is truly the beginning of treatment.

Although tests show no abnormalities, the child's abdominal pain is clearly real. We shouldn't deny that reality, but rather consider how to understand the signals from the child's body.

If it's not just a one-time pain, then that pain is trying to tell you something. As parents, what we need to do is listen to what it's saying.

I have met many patients who came after visiting multiple medical institutions and departments for persistent or recurrent conditions. Symptoms normally handled by different specialties—such as abdominal pain, headaches, palpitations, dizziness, and insomnia—may overlap in one person. Sometimes there is no clear improvement despite taking medication for each symptom, and being unwell gradually becomes part of daily life. In these cases, I look beyond individual diagnoses and examine how the symptoms connect and change together. Asking only about the most uncomfortable symptom today does not reveal the full course. I look at when the body first began to change and what happened after illness, surgery, childbirth, or starting and stopping medication. I also review changes in weight, diet, and sleep, then trace which symptoms improved with previous treatment and which remained. Test results, diagnoses, and the course of previous treatment are important for understanding the current condition. Clinical research in modern Korean medicine, physiological and pathological research in modern medicine, and observations recorded in classical Korean medicine texts offer different perspectives on the same body. Rather than fitting a patient into one perspective, I consider what each can and cannot explain and look for clues that connect symptoms and treatment histories that were previously considered separately.
